ABSTRACT:
A fiber gain medium assembly is provided. The fiber gain medium assembly includes a fiber gain medium, which in turn, includes a longitudinally extending inner core. The fiber gain medium also includes a cladding layer and a photo-emitting conductive polymer, both of which surround the inner core and extend longitudinally therealong. In this regard, the photo-emitting conductive polymer can surround the cladding layer to thereby surround the inner core. Alternatively, the cladding layer can comprise the photo-emitting conductive polymer. The fiber gain medium assembly can also include an electrical system electrically coupled to the photo-emitting conductive polymer. The electrical system is capable of providing an electric field to thereby excite the photo-emitting conductive polymer to emit photons capable of propagating into the inner core and producing gain for the signals propagating through the inner core.
